Title: Improvements in or relating to the packaging of lamp black or like material
IPC: B65B1/24
Filed: 1947-12-30
Abstract: 655,368. Packaging. CHAMPION & CO., Ltd., C. H., and KOPPEL, L. Dec. 30, 1947, No. 34719. [Class 94(i)] In a method of packaging carbon black into a container, wherein air is evacuated from a chamber containing a charge of the black, the chamber is constituted in part by permanent apparatus and in part by the container, the black is compacted within the chamber by pressure, and the container with its charge is subsequently removed from the packaging apparatus. In the example a paper bag 2 is placed like a cap over the bottom open end of a cylinder 1 and clamped against the cylinder by a false bottom 3 mounted on a rod 12 and pressed upwardly by a hydraulic plunger sliding in a cylinder 13. The charge is fed from a hopper 6 to a conical part 1a of the chamber which is subjected to vibration by an electro-magnetic device 8 so that when the evacuation of the cylinder 1 (through a pipe 7), is complete, the whole of the charge will be within the cylinder 1. A plunger 4 now descends and compacts the black. When the black has been fully compacted, Fig. 3, the upward pressure on the false bottom is reduced so that the plunger presses it with the bag and charge downwardly. In its raised position the plunger 4 is drawn into a shield 14 fixed to the underside of the cylinder top, thus preventing the black from adhering to the plunger or lodging on the top thereof while being admitted from the hopper 6. The plunger 4 is mounted on a rod 10 having at its upper end a hydraulic plunger sliding in a cylinder 11. The control of the admission and exhaust of pressure liquid for the cylinders 11 and 13 is automatic, as also is the control of the admission of black from the hopper to the chamber, the subsequent sealing of the chamber from the hopper and the starting and stopping of the air evacuation. The cylinder 1 may be of circular, square or other section. According to the Provisional Specification the false bottom 3 may be biassed upwardly by a strong spring. Specifications 551,862 and 618,955, [both in Group III], are referred to.

Title: Programmable sequence controller
IPC: G06F7/00
Filed: 1973-07-24
Abstract: 1436236 Automatic programmable sequence controllers TOYODA-KOKI KK 24 July 1973 [31 July 1972] 35123/73 Heading G3N A programmable sequence controller includes a clock-pulse generating circuit 10 which produces a plurality of different pulse trains see Fig. 3 (not shown) one of which is used to step program counter 11 to address memory device 12 in sequence unless a jump instruction is received. The memory 12 is a read/write magnetic core memory and contains instructions which are entered by the read-in device 13 and a read-out during operation into the command register and de-coder 14 where the instruction is temporarily stored. The various command signals from register 14 are sent, as appropriate, to the input circuit 16, output circuits 17, 18 logic circuit 15 and the jump circuit 19. The arrival of the command signal at input circuit 16 causes a machine state signal to be sent to the logic circuit for examination. The result of the examination allows the signal to pass to the output holding circuit 18 to set or reset a bi-stable which can then be commanded by circuit 17 to energize or de-energize the respective relay CR1-n and thus control the machine 21. The input converting circuit converts and transmits the machine state information stored by relay contacts S1-n to the input of the logic circuitry. The examination process using logic elements is described in detail with reference to Fig. 2. The process consists of examination by a logical AND function followed by a logical OR function and the results are separately stored in memories. This is followed by a further logical OR examination and this result also is temporarily stored until all three results are identified by an identifying circuit and a command output accordingly.

Title: Process for the preparation of food products from sugar beet vinasses
IPC: A23L27/10
Filed: 1961-09-29
Abstract: Food products are made by the hydrolysis, under decidedly acid conditions, of sugar beet vinasses, i.e. the products obtained by concentrating liquids remaining after the fermentation in distilling operations or yeast production of molasses derived from sugar beet, and, on completion of the hydrolysis bringing up the pH to 4.5-7. Hydrochloric acid is preferred for the hydrolysis. The pH adjustment is made by alkali metal or alkaline earth metal hydroxides, carbonates, bicarbonates, sulphites, bisulphites or metabisulphites. If no sulphite is used, the pH adjustment is made in the cold; if a sulphite is used, sulphur dioxide is eliminated by bubbling air through the product.  Examples are of the preparation of palatable, nourishing liquids containing betaine, glutamic acid, aspartic acid, glutamine, asparagine, leucine, alanine and cystine from crude yeast vinasse, and from such vinasse clarified by centrifuging, by treatment with hydrochloric acid at 90-95 DEG  C. for 5-7 hours.  The products may be used as a nutrient alone, as seasoning, in sauces, or in foods such as dry yeast, meat extracts, vegetable extracts, starches and fats.
